Beijing Kehua Microelectronics Materials Co., Ltd. is a Sino-US joint venture established in 2004. It is a supplier of photoresist and supporting reagents covering KrF (248nm), I-line, G-line, UV wide spectrum photoresist and supporting reagents. It is also a high-tech enterprise with independent intellectual property rights integrating the research, production and sales of advanced photoresist products. Kehua Microelectronics has a mid-to-high-end photoresist production base, including a 100-ton cyclized rubber-based ultraviolet negative photoresist and a thousand-ton negative photoresist supporting reagent production line, and a G/I line positive rubber production line (500 Ton/year) and positive adhesive supporting reagent production line (1000 tons/year), and 100-ton 248nm photoresist production line.

Kehua Microelectronics photoresist product series is complete, and its product application areas cover integrated circuits (ICs), light emitting diodes (LEDs), discrete devices, advanced packaging, microelectromechanical systems (MEMSs), etc. Product types cover KrF (248nm), G/I line (including wide spectrum), mainly including: KrF photoresist DK1080, DK2000, DK3000 series; gi line photoresist KMP C5000, KMP C7000, KMP C8000, KMP EP3100 series and KMP EP3200A series; negative glue KMP E3000 series used in the Lift-off process; BN, BP series used in discrete devices, etc.

Kehua Microelectronics has strong R&D technology, has many photoresist experts, and has strong ability to synthesis, formula and related basic evaluation of photoresist raw materials; it can continue to launch new products that meet customer needs; Kehua Microelectronics has been established by itself Since then, it has undertaken a number of national and Beijing-level photoresist key research and development and industrialization projects.

Kehua Microelectronics has a complete analysis and application testing platform that supports product research and development and factory inspection. The company has two mini FABs, including ASML PAS5500/850 scanning exposure machine with resolution of 0.11um, Nikon stepping exposure machine, TEL ACT8 glue-coating development machine and Hitachi S9220 CD SEM and other mainstream equipment. The above-mentioned test platform ensures that Kehua can carry out the development and comprehensive evaluation of KrF, G/I line photoresist products and key raw materials.

Kehua Microelectronics Management System is complete, with four systems: Quality Management System (ISO9001), Environmental Management System (ISO14001), Occupational Health and Safety Management System (ISO45001) and Hazardous Substance Process Management System (IECQ QC080000). Kehua microelectronics products have advanced technology, own several domestic or international patents, and have stable product quality. They are SMIC, Shanghai Huali Microelectronics, Yangtze Memory, China Resources Shanghua, Hangzhou Shilan, Jilin Hua Microelectronics, San'an Optoelectronics Stable partners for well-known customers in the industry such as Huacan Optoelectronics. After more than ten years of development, the company has a considerable scale and brand influence. The company will be committed to becoming a supplier and service provider of advanced photoresist products.
